SMTP Auth problem

Now I have SMTP auth problem. When I try to send mail via my own mail server. And put require auth for smtp it doesn't accept my password on thunderbird it's just keep asking it again and again, and it doesnt send my mail.

1. If you install latest updates including latest kernel right after you have installed SuSe you have to do restart to your computer otherwise you get error while making quota at command quotaon -avug (something like kernel not supporting)

2. Installing Proftpd do "make clean" and then "make install". Otherwise you could get errors. (time hasling)

I had a smiliar problem after following Falko's (excellent) guide. Got it to work after changing the auth method in /etc/sysconfig/saslauthd:

SASLAUTHD_AUTHMECH = shadow

(this was set to PAM before)

Since the change everything works perfectly. You can verify your user/pass with 'testsaslauthd -u user -p passwd'
I think this should also work with PAM, but then you have to provide an appropriate conf in /etc/pam.d for smtp (PAM ist the Suse standard for authentication)

I was having similar but odd problems with postfix related to this. I am using SuSE 9.2 and followed the perfect setup instructions. I would get my mail when I opened the client and the web interface worked fine. But if I would hit send/recieve in my client I would get errors.

My mail log shows the exact same errors as yours, but chainging from pam to shadow did not work for me.
